Hello, long time lingerer, first time poster. Has anyone ever heard of the i7-2620QM? Its a sandy bridge chip apparently. According to this it was never put into a retina macbook. The reason I ask is because I am considering buying this MC975CH. Fake products are all too common in China, so when I see a rMBP based on a chip that isn't listed on wikipedia, I get suspicious. I want a 15 inch retina not for the processor or gpu, but for the form-factor, so an older model would technically be perfect for me, especially at $1600 USD. I built a desktop on a i5 2500K sandy bridge and I rate it highly. I'm thinking that if this is a legit Chinese model based on old (maybe surplus) chips then it could be a bargain. Or it could be a disaster waiting to happen. Any thoughts appreciated!
